Nucleoside dialdehydes were obtained by periodate oxidation of adenosine, cytidine, guanosine, uridine or 6-azauridine in the presence of Dowex (1x8; CH3COO-). Reductive alkylation of daunorubicin with these dialdehydes in the presence of NaBH3CN produced a series of 3'-deamino-3'- (4-morpholino)daunorubicin or 13-(R,S)-dihydrodaunorubicin derivatives, the latter being mixtures of two diastereomers at 13-C atom. The morpholino- daunorubicin derivatives containing nucleic base moieties are less cytotoxic than cyanomorpholino-daunorubicin, morpholino-daunorubicin and even than the parent antibiotic.
